Unexplained heat-wave ‘hotspots’ are popping up across the globe

by Columbia Climate School, Nov 26, 2024 in ScienceDaily

Summary :  A striking new phenomenon is emerging: distinct regions are seeing repeated heat waves that are so extreme, they fall far beyond what any model of global warming can predict or explain. A new study provides the first worldwide map of such regions, which show up on every continent except Antarctica like giant, angry skin blotches.

Earth’s hottest recorded year was 2023, at 2.12 degrees F above the 20th-century average. This surpassed the previous record set in 2016. So far, the 10 hottest yearly average temperatures have occurred in the past decade. And, with the hottest summer and hottest single day, 2024 is on track to set yet another record.

All this may not be breaking news to everyone, but amid this upward march in average temperatures, a striking new phenomenon is emerging: distinct regions are seeing repeated heat waves that are so extreme, they fall far beyond what any model of global warming can predict or explain. A new study provides the first worldwide map of such regions, which show up on every continent except Antarctica like giant, angry skin blotches. In recent years these heat waves have killed tens of thousands of people, withered crops and forests, and sparked devastating wildfires.

“The large and unexpected margins by which recent regional-scale extremes have broken earlier records have raised questions about the degree to which climate models can provide adequate estimates of relations between global mean temperature changes and regional climate risks,” says the study.

“This is about extreme trends that are the outcome of physical interactions we might not completely understand,” said lead author Kai Kornhuber, an adjunct scientist at the Columbia Climate School’s Lamont-Doherty Earth Observatory. “These regions become temporary hothouses.” Kornhuber is also a senior research scholar at the International Institute for Applied Systems Analysis in Austria.

The study was just published in the journal Proceedings of the National Academy of Sciences.

Climbing overall temperatures make heat waves more likely in many cases, but the causes of the extreme heat outbreaks are not entirely clear. In Europe and Russia, an earlier study led by Kornhuber blamed heat waves and droughts on wobbles in the jet stream, a fast-moving river of air that continuously circles the northern hemisphere.

Greenland Surface Temperatures Fall for 20 Years in Fresh Blow to Climate Alarm Narrative

by C. Morrison, Nov 27, 2024 in WUWT

Further evidence that surface temperatures across Greenland have been cooling for around 20 years has emerged with the recent publication of findings from a group of Thai scientists and mathematicians. Processing 31,464 satellite recording from 2000-2019 over the entire area, they found that the average temperature fell by 0.11°C. This is said to indicate a “non-significant change in LST [land surface temperature]”. The latest evidence of actual cooling over a significant area of the Arctic will not be news in scientific circles since it backs up previous findings of recent temperature falls. But the information is of course kept out of the mainstream since it casts doubt on the key Net Zero scare about soaring sea levels caused by the catastrophic melting of the Greenland ice sheet.

There are some crumbs of comfort for alarmists since the Thai authors found that the ice-free sub-regions of Greenland are warmer than the ice-covered sub regions. But perhaps not – the authors attributed it to “population density”. Urban heat yet again corrupting the temperature data, even in Greenland. The illustration below charts the temperature record for all areas of Greenland.

The World Economic Forum recently reported on a study that predicted a “total collapse” of the Greenland ice sheet within a few months. This suggestion is only slightly more ludicrous than the scares routinely published to induce mass psychosis in populations with the aim of promoting a collectivist command-and-control Net Zero solution. The recent farce around the COP in Baku showed the conspiracy operating in plain sight. Stop the developing word developing with hydrocarbons, then invent a number of fake scares such as island states disappearing beneath the waves. Everyone knows this and most of the other scares are false as scientists have shown on numerous occasions, but no matter. Invent some ridiculous composite figure – say $250 billion a year, or $1.3 billion by 2035 – then pretend your taxpayers can be rinsed even though the only country that could conceivably afford it is leaving the party in January.

COP 29 diplomacy delivers perfectly vague promises a decade away

by  D. Wojick, Nov 25, 2024 in WUWT

In Cop 29’s “Finance agreement” diplomacy is truly the art of agreeing to nothing. There is no agreement of substance here because there is no substance to this agreement. Each side gets its number someday and that is all there is to it.

Let’s look at the actual text to see the nothing. But first recall what was supposed to happen. The Paris Agreement committed the developed country members to providing $100 billion a year to the developing countries through 2025. COP 29 was simply supposed to revise that annual payment up beginning in 2026. That did not happen, not even close.

The fiasco started when the developing countries demanded huge impossibly sums centered on $1.3 trillion. That set in motion a series of side steps leading to the present agreement which is very different from the intended goal.

To begin with the $1.3 trillion annual payment is there but it is “by 2035” so ten years from now not in 2026. I can see delaying it until a few years after Trump leaves office but these folks are wedded to their five year plans.

Moreover this money need not come from the developed countries and certainly not from their governments. First it is to come “from all public and private sources.” Second the eligible sources have been expanded to include all the developing countries as well as the developed ones.

These two provisions have fundamentally changed the concept of climate finance. It used to just include mostly government money going from developed to developing countries. Now it sounds like any climate related investment or contribution that winds up in a developing country counts.

Working this out will be supremely challenging. For example if China builds itself an offshore wind array, and they are building plenty, is that climate finance? How about if they build it in Indonesia?

Oh and it looks like coal fired power plants count too. In early drafts of the agreement counting coal plants was ruled out because people were doing that in the name of adaptation. Having electricity certainly helps when extreme weather hits. But that prohibition does not appear in the final agreement so the practice looks allowable.

Then there is the other big number, the $300 billion a year. This is widely assumed to replace the $100 billion a year mandated by the Paris Agreement through 2025. For example CBS has a headline that yells “deal reached at UN’s COP29 climate talks for $300 billion a year (up from $100 billion).”

This is incorrect as here too the new agreement says the goal is “by 2035.” Nor is all (or any) of this distant sum necessarily coming from developed countries as the yearly $100 billion had to. The new agreement just says “with developed country Parties taking the lead.” (Parties means to the Paris Agreement.)
